MySQL 企业备份用户指南（版本 8.0.31） / 第二部分使用 MySQL 企业备份 / 第 4 章备份数据库服务器 / 4.2 典型的备份/验证/恢复周期 /
4.2.2 备份整个MySQL实例
在下面的示例中，我们使用命令将整个 MySQL 实例备份到单个文件，该
backup-to-image命令出现在示例命令的末尾。--user我们使用和--host选项指定数据库的一些连接信息
（并使用该--password选项告诉 MySQL 服务器提示输入用户密码）。单个文件备份的位置和文件名使用该
--backup-image选项指定，用于存储临时文件的空文件夹的位置由该--backup-dir
选项提供。
输出回显备份操作使用的所有参数，包括使用数据库连接自动检索的几个参数。此备份作业的唯一 ID 记录在 mysqlbackup在 MySQL 实例中创建的特殊表中，允许您监视长时间运行的备份并查看以前备份的信息。最后的输出部分重复了备份数据的位置，并提供了 LSN值，您在下次对 刚刚创建 的完整备份执行 增量备份时可能会用到这些值。
$ ./mysqlbackup --user=root --password --host=127.0.0.1 --backup-image=/home/admin/backups/my.mbi \
--backup-dir=/home/admin/backup-tmp backup-to-image
